CONCORD — A former DMV employee is facing felony charges after an internal investigation determined she issued several drivers licenses to people who hadn’t earned them.

Gwenell Williams, 59, was charged with felony charges of public records violation and computer access fraud, as well as misdemeanor charges of wrongfully accessing government documents. She pleaded not guilty at her February arraignment, court records show.

According to police, the investigation started after the DMV received tips that Williams, a clerk at the Concord DMV office, had issued licenses that were deemed suspicious. By the investigation’s end, authorities identified more than 20 license issuances that appeared suspicious, court records show.

Investigators reviewed surveillance footage of the DMV office during some of the suspicious transactions, and found that Williams appeared to be sending text messages to people immediately before and after issuing the licenses. During several of the issuances, the people who received the licenses weren’t even at the DMV, according to authorities.

Some of the licenses were recorded as having been issued by a clerk who didn’t exist, authorities said.

When authorities interviewed Williams, she allegedly admitted to working with two “drivers license brokers” named “Jazz” and “Remi,” who would text her to complete a license under a certain person’s name by marking them as having passed driving tests. Williams said she would often bypass the fingerprint requirement and simply send the licenses through normal DMV mail, authorities said.

Williams allegedly admitted to having done several of these transactions over the course of two years. She denied getting monetary payments for it, but admitted she had accepted small amounts of marijuana as a gift, according to court records.

A DMV spokeswoman said Williams is no longer employed by the agency.

“The DMV does not comment on pending cases. Broadly speaking, the DMV takes fraud in the workplace very seriously and has a zero-tolerance policy,” DMV deputy director of public affairs Anita Gore said in an email.
